It is great exciting news for our high pressure science community in Japan that the first pulsed neutron beams were delivered to J-PARC Materials & Life Science Experimental Facility (MLF) on May 30th, 2008. We believe that the newly dedicated pulsed neutron beams will open a new window in the high-pressure science world. Over the past 7 years, we have prepared some projects to build a high pressure and high temperature material science beamline in the MLF. In this article, we will give a brief overview of the progress of those projects and also introduce a newly designed high-pressure cell and a neutron focusing mirror for in-situ neutron diffraction experiments at high pressure and high temperature.
